Power Bank Capacity Clarification

The rated capacity (e.g., 10,000mAh) is measured at the battery's voltage of 3.7V. Since your phone charges at 5V, energy is lost during this necessary voltage conversion.

Therefore, the actual useful output capacity is typically 60-70% of the rated capacity.

*Example: A power bank rated at 10,000mAh can deliver approximately 6,000-7,000mAh to charge your device.*
